`tpeeifcation of Batters-Patent. Patented Sept. Q8, 1909.

Application led Hay 7, 1909. Serial No. 494,573.

To all whom 'it may concern:

Be it known that I, WILLIAM BUNTING,

Jr., of Brookline,`county ofl Norfolk, State of Massachusetts, have invented an Improvement in Lavatories, of which the following is a specification.

This invention relates to certain improvements in lavatories of the character shown in my pendlng application Serial No. 470,942,1iled January 6,- 1909, in which a raised or thickened portion is formed in the slab in the rear of the bowl, within whicha discharge waterway is formed, which leads rearwardly and opens at the under side of the slab at two points to receive the hot and cold water supply pipes.

The object of the present invention is to provide a form of bowl of the general character above referred to, in which the hot and cold water supply pipes are united in a single pipe on or before entering the slab and, also, to adapt a valve, suchas 'is shown in my prior patent #682,453, dated February 10, 1901, to the purpose.

A further object of my invention isto provide a simple and ei'ective form of connection between the valve casing and the bowl.

lI accomplish these objects by the means shown inthe accompanying drawing, in which,

Figure l is a front elevation of the rear portion of a bowl provided with my invention. Fig. 2 is a cross section on the line 2-2 of Fig'. 1. Fi 3 is a cross section on the line o-3 of Flg'. 2. Fi 4 is a cross section, on the line correspon ing to the line 2--2 of Fig. 1, of a modified form of my invention. Fig. 5 is a cross section o n the'line 5-5 of Fig. 4.

According to my invention the slab a is formed integral with the rear wall b of the bowl, and projects rearwardly from said wall, so that a clear space is provided in the rear thereof, and beneath the slab. Said slab may be rovided with a depending strengthening ange a', iis-indicated, which, however, bears no relation to my invention.

According to my invention I provide a raisedl portlon a2 on the uV per side of the Velab directly in the-rear of t e middle of the Vbow said raised portion being' provided with ai passage a, which extends rearwardly o1" longitudinally of said raised portion in the central vertical lane of the bowl, said assageextending o iquely downward at its ront end and opening into theA bowlA approximately at the level of-its rim. Said passage a3 extends rearwardly in the slab for some distance beyond the outer side of the rear wall of the bowl, and an aperture a* is provided in the slab, which leads from I the rear end of said passage a3, to the under side thereof, while an aperture a5 is provided which leads through said raised portion to its upper side, from the rear, end of said passage as, saidapertures a4 and a5 being arranged in alinement.

A valve is provided, of the character shown in my prlor patent, above referred to, the casing c'of said valve extending through said apertures a4L and a5, and being connected at its lower end to hot and cold water supply pipes d and e, in which valves d', e are provided, which are controlled by stems extendingv up through the casing and connected to.L handles d2, c2 at their upper ends. The waste operatingl rod f, which :1s connected to the handle f', also extends downwardly through the casing, as shown in my said prior patent.

A packing washer is provided between the upper ange c oig the valve casing and the upper side of said raised portion a2, and an expansion ring/L, of rubber, is provided on the casin between an abutment ring i, and a'clampln Y nut j, both threaded on the lower end of t ie casing the external diameter of said ring i being less than the internal diameter of said aperture a", and said nut j bei adapted' to engage the under side of the s ab about said aperture at. In applying .said valve to the lavatory, the casing c is passed down through the apertures a5, on4 and the ring z' is so adjusted that, when the nut j is screwedv onto the casing the rineh will be compressed axiall and expan Kd until the periphery thereo is forced irmly against the Walls of the aperture at, before the nut j engages the under side of the slab andV draws the gasket g, at the upper end of the casing, firmly against the seat therefor, on the raised portion about the upper end of the aperture a5.- A; tight joint will thus be formed at both the upper end of the aperture a-5 and the lower end kof the aperture a, thereb preventin the escape of water from sai chamber w en water 1s admitted thereto. The supply pipes are then connected to the casin in a manner which wilt be obvious, the w le arrangement being such that said connections may be conveniently made.

In the modification of Figs. 4 and 5, the raised portion a2 is provided with a rearwardly eXtendin passage a3", and an aperture a is provi ed which extends from the rear end of said passage an3o to the under.`

vside of the slab, as above described, except that no opening is provided to the upper side of the' raised portion. With this arrangement a branch pipe m is connected to the aperture a by a suitable expansion joint m", and the lower end of said pipe m ibowl, said stems being is connected by a suitablemeans, as the T- coupling shown, to two branch pipes m and m2, said branch pipes bein respectively connected to valves n and o, t e stems n and o of which extendvertically through the slab at points equidistantfrom the middle of the provided with operatin handles n2, o2, above the level of the sla The hot and cold water supply pipes p and g /are respectivelyconnected to the valves n and 0, anda waste o erating rod 1'/ is provided in the `slab direc the passage a2 and inthe central plane of the bowl. This form of my invention is less expensive of manufacture, than the form previously described, and the connections maybe made without difficulty.

'Having thus described my invention, what I claim as new and desire to secure vby Letters Patent is 4 1.
